And a cotton fiber knitted fabric treated with the processing agent.
편성물의 탄성을 증가시키기 위하여 탄성가공제로 탄성실리콘오일유화제품, 수용성 우레탄제품을 사용한다. 그러나, 상기 탄성실리콘오일유화제품은 촉감(soft touch)이 우수하지만 탄성력과 방오성이 미흡한 단점이 있다. 상기 수용성 우레탄제품은 탄성력과 흡한ㆍ속건의 특징을 가지고 있으나, 촉감(soft touch)이 미흡한 단점이 있다. In order to increase the elasticity of the knitted fabric, elastic silicone oil emulsified products and water-soluble urethane products are used as elastic processing agents. However, the elastic silicone oil emulsified product has a soft touch, but has a disadvantage of insufficient elasticity and antifouling property. The water-soluble urethane product has the characteristics of elasticity, sweat absorption and quick-drying, but has a disadvantage in that soft touch is insufficient.
